Pollination by flies, known as myophily, is the second most prevalent method of pollination among orchids, involving pollinators from twenty different dipteran families. [13] These flowers typically emit scents reminiscent of decaying organic materials, excrement, or carrion, which attract flies seeking food or suitable sites for egg deposition ...
The complex mechanisms that orchids have evolved to achieve cross-pollination were investigated by Charles Darwin and described in Fertilisation of Orchids (1862). Orchids have developed highly specialized pollination systems, thus the chances of being pollinated are often scarce, so orchid flowers usually remain receptive for very long periods ...
Orchids can be found on every continent except Antarctica. ... The pouch shape aids in pollination. Pollinators are attracted to the flower’s sweet scent and fall into the pouch, getting trapped ...
A pollinium (pl.: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. [1] [2] This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen ...
They are referred to as the "bee orchids" due to the flowers of some species resemblance to the furry bodies of bees and other insects. Their scientific name Ophrys is the Greek word for "eyebrow", referring to the furry edges of the lips of several species. [4] Ophrys was first mentioned in the book "Natural History" by Pliny the Elder (23-79 AD).
Fertilisation of Orchids is a book by English naturalist Charles Darwin published on 15 May 1862 under the full explanatory title On the Various Contrivances by Which British and Foreign Orchids Are Fertilised by Insects, and On the Good Effects of Intercrossing. [1]
The disadvantages of self-pollination come from a lack of variation that allows no adaptation to the changing environment or potential pathogen attack. Self-pollination can lead to inbreeding depression caused by expression of deleterious recessive mutations, [2] or to the reduced health of the species, due to the breeding of related specimens ...
Ophrys like other orchids are dependent on symbiotic fungi at some point during their life cycle, but especially for germination, which may take months or even years underground. Orchid roots contain orchid mycorrhiza , coils of fungal hyphae inside orchid root cells.
